Probing topological degeneracy on a torus using superconducting altermagnets
Tsz Fung Heung, Marcel Franz
The notion of topological order (TO) can be defined through the characteristic ground state degeneracy of a system placed on a manifold with non-zero genus , such as a torus. Th…
Zero Bias Conductance Peak in Dirac Semimetal-Superconductor Devices
W. Yu, Rafael Haenel, M. A. Rodriguez +5
Majorana zero modes (MZMs), fundamental building blocks for realizing topological quantum computers, can appear at the interface between a superconductor and a topological material…
Quantum holography in a graphene flake with an irregular boundary
Anffany Chen, R. Ilan, F. de Juan +2
Electrons in clean macroscopic samples of graphene exhibit an astonishing variety of quantum phases when strong perpendicular magnetic field is applied. These include integer and f…
Josephson current signatures of the Majorana flat bands on the surface of time-reversal-invariant Weyl and Dirac semimetals
Anffany Chen, D. I. Pikulin, M. Franz
A linear Josephson junction mediated by the surface states of a time-reversal-invariant Weyl or Dirac semimetal localizes Majorana flat bands protected by the time-reversal symmetr…
Quantum oscillations without magnetic field
Tianyu Liu, D. I. Pikulin, M. Franz
When magnetic field is applied to a metal, nearly all observable quantities exhibit oscillations periodic in . Such quantum oscillations reflect the fundamental reorganiza…
Interaction-enabled topological phases in topological insulator-superconductor heterostructures
D. I. Pikulin, Ching-Kai Chiu, Xiaoyu Zhu +1
Topological phases of matter that depend for their existence on interactions are fundamentally interesting and potentially useful as platforms for future quantum computers. Despite…
